Abstract
This chapter focuses on an example of domestic Drosophila species living on a divided and ephemeral resource and seeks to demonstrate how the spatial organization of a population may serve to reduce population fluctuations on a 'global' scale. Laboratory experiments are described which demonstrate that Drosophila laboratory cultures show population fluctuations. The same experiments provide estimates of the type and strength of density-dependent mortality on a local scale. When these parameter values are put into a local competition model, the predicted and observed dynamic behaviour are in qualitative agreement. A simulation model for a global population of a single species living on a divided and ephemeral resource is presented and a stability analysis of the model performed. Finally, the discussion considers other related work on the effect of patchiness on stability.
